So video doorbell. I have the app.So video doorbell. I have the app. if I hit "siren" I know it turns on but how do I turn it off? If it is on, the instructions say to "tap the slider" to turn it off but there is no off option Do I have to pay for a plan to be able to turn the siren off and on? Help if you can please. I've looked everywhere and cant figure it out
